Dometic refer - Door flange condensation heater

[BruceMc]

I've been searching for the posting where the wires entering the lamp/switch box can be cut to disable the condensation heater.

Mine doesn't have the factory switch, so I wanted to snip & cap off the wire to the heater strip. There's a larger and smaller wire on both the red and back wires. Logic would say to snip the heavy wire, but I think that's the power lead in. The heater strip probably is the smaller wires.

Can someone (re)educate me on this - and/or post a link to the original post?

Thanks in advance!

Perfect, SoundGuy! That's exactly the information I was looking for.

Take care, and RV on!

The thicker of the 2 red wires going to the fridge light feeds power to the climate control circuit. I wired in as SPST toggle switch but you could just cut the wire if you don't intend to ever have the heater on.

DFord, don't jump to conclusions about my usage model - We'll be boondocking for a few days, and not yet having solar, I'm trying to make the most efficient use of the batteries while we are in the dry high desert. I'll make the decisions about when I want the heater to run, and when I want it turned off.

The heater strip is wired in parallel to the light/switch on most of these models.

You really need to look at the specific wiring diagram on yours- Dometic wired these differently, depending on the product number (not model number).

Keep in mind that heater is there for a purpose. It's there to prevent condensation. Any time the dew point is higher that the surface protected by the heater, there will be condensation occurring leading to rust sooner or later. There in the Wilmette Valley, dew points are regularly in the 50 to 60 degree range. When in desert areas where the dew point is below 25 degree condensation won't be an issue and those with a switch could safely turn the heater off. Around St Louis where I live, we often have dew points near and sometimes over 70 degrees so those heaters are a must.
